IMPROVEMENT IN CARTRIDGE-WEIGHING MACHINES.

Specification forming part of Letters Patent No. 185,858, dated January2, 1877; application tiled November 3, 1876.

To all whom it may concern:

Be it known that I, JABEZ H. GILL, of Philadelphia, in the State ofPennsylvania, have invented a new and useful Improved Machine forWeighing Cartridges; and that the following is a full, clear, and exactdescription thereof, reference being bad to the accompanying drawings,making a part of this specification, and to the letters of referencemarked thereon.

The object of my invention is to separate those cartridges which havetoo little powder in them from those which have sufficient, and throwthem to one side. To this end my invention consists of a revolving disk,supported upon a base provided with guiding ways or tracks; said diskbeing supplied with any desired number of weighing-scales, the trays ofwhich are tilted by suitable mechanism at the desired point, wherebythose shells which contain too little powder are deposited in one place,and those containing a sufficient quantity are deposited in anotherplace, all which will be more fully hereinafter explained.

Figure I is a perspective view of my invention. Fig. II is a plan viewof the same. Fig. III is a vertical central section of the same and Fig.IV is a vertical section, showing the details of the weighing-scales,and the guiding-ways or tracks which operate the scale.

In the drawings, B represents a base, which may be hollow, andperforated to receive the pivot or spindle F, to the lower end of whichmay be secured a pulley, F, with the disk A secured to the upper end.This disk is provided with any desired number of recesses, a, to receivethe scales or balances N, which consist of the forked beam b, upon theinner end of which is placed the counterpoise 0, made adjustablethereon, either toward or from the pivot n, upon which the beam isbalanced, and which pivot should have a knife-edge on the lower side, asshown in Fig. III, that it may be sufficiently delicate in itsmovements. Nicely balanced upon trunnions or pivots h, atthe forked endof the beam b, is the pan or tray 0, with a trip' or projecting piece,f, on its lower side; and a small wheel, g, may also be attachedthereto, near the trip, and also one at the inner end of the tray, ato,- and another similar wheel may be attached to the lower side of thecounterpoise G, to permit the tray and counterpoise to ride aroundfreely upon their tracks made upon the base B of. the machine, as shownat c c and s in Figs. II and IV. These tracks are made only partiallyaround the base, as shown in dotted lines in Fig. II, and are beveled attheir ends to permit the tray and counterpoise to ride gently from andupon them. The track 0, which extends around beneath the outer end ofthe tray, is somewhat higher than the track a, beneath the inner end ofthe tray, as seen clearly in Fig. IV, and the tray assumes a tiltedposition, as seen in Fig. IV, after riding up over the beveled ends ofthese tracks. Apertures m are made in the disk, beneath thecounterpoise, so that a projection upon the latter, at m, or the wheelattached thereto, may protrude through and bear upon the track .9, whenthe scale is passing around to receive the shell, to hold the scale in aproper horizontal position, and when the tray is empty the counterpoisemay rest upon the bottom of the central recess V of the disk, to preventany unnecessary movement of the scale.

The operation of my invention is as follows: The disk A, which may beprovided with any desired number of scales, as indicated by the recessesa, is given a rotary motion in the direction indicated by the arrow, bya belt passing around the pulley F, or by any other suitable means, andas the scale N in each recess rides up on to the tracks 0 and c, or atany point in the length of the line B, in Fig. II, the shell, with theproper quantity of powder therein, is placed in the tray 0, and, withthe counterpoise G, adjusted on the inner end of the beam b, so that theminimum quantity of powder required in the shell will just overbalancethe counterpoise 0. As the disk A rotates, with the shell in the tray,as long as the latter rides upon the tracks 0 and c, it maintains atilted position, as shown in Fig. IV; but when each scale arrives at thepoint It, or passes off the tracks, it assumes a position shown in Fig.III, and as it passes around the projection f strikes against thetripping-grade E, and the tray is thereby tilted, and the shell thrownout at the point E. If, on the other hand, an insufficient quantity ofpowder is placed in the shell, when it arrives at the point R the weightof the powder and shell will not be suflicient to overbalance thecounterpoise, and the scale, instead of falling, maintains itshorizontal position, or even slightly rises at the tray end, and theprojection f passes along above the grade E, and on reaching thetripping-grade E strikes against that, which is higher, as shown in Fig.111, and the tray is tilted, and the shell thrown out at I.

It will thus be seen that a shell which contains less than the requiredminimum quantity of powder is thrown out at one point, and separatedfrom those which contain the minimum quantity, which are thrown into aplace by themselves.

It will be observed that the tray 0, when free from the tracks 0 and 0,always assumes a horizontal position, whether that end of the beam risesor falls, being nicely balanced upon the trunnions or pivots h for thatpurpose.

It is obvious that the disk may be made of any size, and may be providedwith any desired number of scales, and may be made to rotate by anydesired means.

Having thus described my invention, what a J ABEZ H. GILL.
